A suspended mailbox stops sending. Suspension is a deliberate action, not an automatic one - InboxLee does not auto-suspend mailboxes. You suspend a mailbox to keep the rest of your domain reputation intact while you investigate.

How to investigate
Open the mailbox page. The Suspension banner shows who suspended the mailbox and when, and links to the relevant signal - the blacklist source, the DKIM status, the bouncing recipient list. Click through to see the underlying data.
How to resume
Once you have addressed the underlying issue (delisted from blacklist, cleaned the list, fixed DNS), click Resume on the mailbox page. Sending resumes immediately at the appropriate warmup-day cap.
If the underlying issue is not fixable (for example a deeply damaged domain reputation), retire the mailbox and provision a replacement on a fresh domain. That is sometimes the right call.
